To L ZZ whom t may concer-71,:

Be it'known that'I, LOUIS MARIE GABRiEL DELAUNAY BELLEVILLE, a citizen of the French Republic, residing at lNeuilly sur Seine, Department of Seine, France, have invented certain new and useful Improvements in Locking Devices, of which the following is a specification.

This invention relates to locking devices, and has for its object toprovide adevice of such class in Aa manner as hereinafter' set forth for lockin or. clutching an operating element to an e ement to be operated and comprises a rocking lever carrying on one eX- tremity a bolt for locking a shiftable element to a driving element and having its other eX- tremity engaged by a uide for moving the bolt end of 'a lever to and from operative position, the arrangement permitting of render- .ing the tWo elements solid or independent,

starting from a given point in the longitudinal' travel of the operat' element.

The device is particul-aly adapted for use in, connection with internal mechanism of change-speed gears for'motor-vehicles; but it may also beused for any purposes wherein it is found applicable. I In describing the invention in detail reference is had to the accompanying drawings, Which form a part of this specification, and wherein like reference characters denote corresponding parts throughout the several views, and in Which- Figure 1 isa longitudinal section through a change-speed gear provided with the clutching device which forms the object ol" the invention. Fig. 2 is a cross -section through the same. Fig. 3 is ahorizontal section through this change-speed gear. Fig. 4 shows the sliding gears and their operating mechanism. Figs. 5 and G represent, in side elevation and front elevation, the bolt-lever; and Fig. 7 is a plan view of the grooved guide serving to operate the" bolt-lever.

This change-speed gear comprises a motorshaft A, upon which is mounted a pinion 1 and the sliding gears 2 3.v The pinion 1 and the gears 2 3V are solid With the shaft A in its rotation, but are capable of longitudinal displacement .upon it. The shaft B tej be driven is, mounted in line with the motorshaft A. It carries at its extremity adjacent caused to mesh. li

pinions ,12 1'3 of the reversing-gear areV fixed..

The gears 4 and 4 are always in mesh. ff For the top speed With direct. drivel'fthe clutch-teeth 32 and 42 are brought intentie/sh.

The gears 2 2" ofl'the For thethird speed the sliding trainiisfdis-efg;

placed in such a manner as tobring thegears 3 and 3 into mesh.. Forthe second speed the gears 2 and 2 are brought into mesh. AFor the iirst lspeed the pinion 1 and gearl are and gear 1l are caused to mesh with the pinions 12 and 13, respectively.

The pinion 1 and the gears'2 3 are 'displaced for producing the different speeds by means of an operating-rod E. The o erating-fork F f the pinion 1 is bolted to t e rod E. fork G, controlling the displace- Inf-nts ci" the gears 2 3, on the other hand, is capable of4 sliding on the rod E and is not capable of displacing the gears 2 3, except when the locking device connects this fork with the rod E. f

The locking means comprises a lever H, capable of rocking 'around a shaft 5, carried by one arm of the forli G. The upper extremity of this lever forms a bolt 6. The lower extremity 7 of the lever is guided in-the groove of a guide K, fixed to the gear-case. The bolt 6 is able to engage in a notch in the fork G and in a recess 6 in the rod E. TWhen the bolt is engaged, the fork G is rendered solid with the rod E, and the displacement of the. rod E insures that of the gears 2 3. When, on the other hand, the bolt is not engaged, it is n o longer in the recess 6 of the rodE and the' gears 2 3 are no longer displaced. The groove in the Guide controls the heel 7 of the lever II, causing it to oscillate or rock aroundy the shaft 5 in order to produce at the` or the reverse the pinion 1 proper moment the engagement or disenagement ofthe head 6, which forms the bolt.

t limits the travel of the fork G in both directions.

f So long as the heel 7 of the lever H is slidmg the bolt '6 is engaged. Vhen, however, the rod E is pressed toward the left hand by a sufficient amount, the heel 7 of the lever H enters the curved part 7 of the groove, the lever rocks around the shaft 5, the bolt 6 is released, and at the same time the heel 7 of y the lever strikes against the extremity of the groove and stops the dis lacement of the Ork G, and consequently t at of the gears 2 3 also. A

In Figs. 1, 2, and 3 the bolt 6 of the lever H is engaged, the gears 2 3 occupy the end of their travel toward the right hand, and the clutchteeth 32 and 42 are in mesh for the top speed on-the direct drive.

In Fig. 4 the bolt Gofthe lever H is released, the r'od E has been displaced toward the left hand. the heel 7 of the lever has' enteredthe curved part 7 of the guide-groove, the bolt has been releasedand the rod E, havcontinued its movement, has displaced o y the pinion l toward the left hand. When the rod E is again moved toward the iight hand, the cheek. of the fork F encounters the gear 2. At this moment the recess 6 of the rod E comes -inst in front ofthe notch in the fork G, the fork F will ush the gears 3 2, the fork G, and the lever II toward the right hand. The heel 7 of the lever H 35 will be gradually brought into the rectilinear in the rectilinear portion of the guide K portion of the groove of the guide K and the olt 6 of the lever H Will enter the recess 6 of the rod E, in which it Will be com pletely embedded as soon as the heel 7 of the bolt is situated in the rectilinear part of the groove in the cam. The fork G, moving the sliding train, is at this moment solid with the operating-rod E. With this arrangement of boltlever and guide-cam the engagement and release take place automatically always at the same point in the travel of the rod E, and 1t 1s lmpossible for the mechanism to get out of order.

Having now particularly described and as certained the nature of my invention and in what manner the same is to be performed, I declare that '.vhat I claim is- In combination, adriving elemen-t, a shiftable and rotatable element carried thereby, a rod, a fork shiftable upon said rod and adapted to engage the rotatable element, a shaft carried by the fork, a lever rocking upon said shaft and having a head constituting a bolt adapted to engage in said rod for connect-ing the fork thereto, and a guide engaged by said lever and adapted to shift the lever in and out of engagement with said rod and to limit the trave of the lever in either direction.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
